WILLIAM. S. DODSON, OF SPRINGFIELD, MISSOURI.

BRAKE SHOE.

Application filed April 28, 1924. Serial No. 709,598.

T 0 all rv/ 10m it may concern:

Be it known that I, VILLTAM S. DODSON, a citizen of the United States, residing at Springfield, in the county of Greene and State of Missouri, have invented new and useful Improvements in Brake Shoes, of which the following is a specification.

This invention relates to a brake shoe, the general object of the invention being to provide means for detachably connecting the shoe with its support so that the shoe can be removed when worn and a new one substituted therefor.

Another object of the invention is to provide a spring key engaging eyes formed in the support and the shoe for holding the shoe to the support.

This invention also consists in certain other features of construction and in the coi'i'rbination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claim.

In describing my invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which 1- Figure 1 is a view showing the invention in use.

Figure 2 is an edge view of the device.

Figure 3 is a longitudinal sectional view through Figure 2.

Figure 4 is a section on line l-=4 of Figure 3.

Figure 5 is a section on line 55 of Figure 3.

In these views, 1 indicates a shoe support, 2 the shoe and 3 the wheel to be braked by the shoe. The support is attached to its carrying member in the ordinary or any desired manner. The shoe is detachably connected with the support so that it can be replaced when worn and the means for attaching the shoe to the support consists of a spring key at which is adapted to be passed through a longitudinally extending groove 5 formed in the support and under the cross pieces 6 which bridge said groove at the center of the support and through the eye 7 formed on the central partof the shoe and which is adapted to enter the space between the bridge pieces 6 of the support when the shoe is in place. The groove 5 forms prongs 8 at each end of the support, the prongs at one end of the support engaging the projection 9 at one end of the shoe and which carries a pin 10 which passes over the prongs and the prongs of the other end of the support pass under the hook-shaped lugs 11 at the other end of the shoe which are spaced apart to permit the key to enter the groove 5 in the support. The key is of tapered formation and its head 12 is arranged to lie between the lugs 11, as shown.

From the foregoing it will be seen that the shoe is detachably connected with the support by the key so that by withdrawing the key the shoe is released from the support so that a new one can be put in place when the old one has become worn. The key is guided into position by the spaced lugs 11 and the prongs at one end of the support and its small end will pass under the bridge pieces 6 and through the eye 7 as it is punched through the groove 5. Thus the shoe can be easily and quickly attached to or detached from the support.

It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent.

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes fall with in the scope of the appended claim.

hat I claim is:

A brake shoe comprising a support and a. shoe, a pin carrying projection at one end of the shoe and hook-shaped lugs at the other end. of the shoe, a support having forked ends for engaging the projection on the lugs and said support having a longitudinally extending groove with pieces bridging the groove, an eye on the shoe for entering the groove between the bridge pieces and a spring key adapted to be passed through the groove and under the bridge pieces and through the eye.

In testimony whereof I aflix my signature.
